Product Description

Whether you want to make your home more energy-efficient or just a cosier place in the winter, addressing thermal bridges should be your first port of call. Celotex TB4040 PIR Insulation 40mm is a BBA certified thermal insulation solution purposed to combat thermal-bridging in a variety of floor, wall and roof applications. The 2.4m x 1.2m boards are made with the environment in mind. Manufactured using polyisocyanurate and blowing agents with zero ozone depletion potential, the boards have zero ozone depletion potential (ODP) and low global warming potential (GWP); meaning they're as soft on the environment as they are hard on thermal bridges, boasting a thermal conductivity of just 0.022 W/m.K.

40mm Celotex PIR boards feature low emissivity foil facings that improve thermal conductivity in sealed cavity air spaces. Celotex TB4040 is also equipped with a BRE Green Guide rating A, which can be used in your BREEAM assessments to show environmental performance.


TB4040 Celotex 40mm PIR Insulation Board Applications


This Celotex insulation board features low emissivity foil facings and is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). Specifically designed to eliminate thermal bridges, (as the 'TB' in its title states), TB4040 is suitable for roof, floor, and wall applications in new buildings or refurbishment projects, giving improved thermal insulation performance within cavity air spaces. Its thermal conductivity of 0.022w W/mK makes it the ideal solution for insulation in pitched roofs, flat roofs, solid masonry walls, timber frames, and steel framed systems. It can also be used in solid floor systems such as screed and concrete slab floors, and as loft insulation between timber rafters. 

Celotex TB4040 can be used in the following construction types:

  • Ground Floor - Concrete Slab (perimeter upstand)
  • Ground Floor - Beam and Block (perimeter upstand)
  • Ground Floor - Suspended Timber Joists (perimeter upstand)
  • Ground Floor - Upgrading Existing Concrete Slab (perimeter upstand)
  • External Wall - Timber Frame Internal Linings
  • External Wall - Masonry Cavity Internal Linings
  • External Wall - Solid Masonry Internal Linings
  • Pitched Roof - Below Timber Rafters
  • Pitched Roof - Above Timber Rafters


Celotex TB4040 Specifications

The Celotex TB4000 range is a cost-effective alternative to brands such as Kingspan, without compromising performance. Celotex TB4040 multi-purpose insulation board is your one-stop solution when it comes to overcoming thermal bridging. Celotex 40mm TB4040 boards were developed as a simple solution to overcome localised thermal bridges by providing a continuous layer of rigid polyisocyanurate PIR insulation within the building structure. 

Let's have a look at the specs:

  • Excellent thermal conductivity of 0.022w W/mK
  • Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces
  • Complies with UK Building Regulations with better U-values and thinner solutions
  • Zero Global Warming Potential (GWP) and Zero Ozone Depleting Potential (ODP)
  • Easy to install
  • BBA certified - Celotex TB4040 has been assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate
  • Achieves a BRE Green Guide Rating of A, which can assist in demonstrating environmental performance in your BREEAM assessments
  • Lightweight 2400 x 1200mm boards


Celotex TB4040 Insulation Board Certifications

BS EN is British and European Standard Specifications. With over 100 years of experience, the British Standards Institute is recognised as the UK’s National standards body.

  • Spread of flame: Euroclass E Reaction to Fire classification, according to BS EN 13501-1
  • Compressive Strength: 140kPa
  • Thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value - BS EN 12667
  • BRE Green Guide Rating of A for sustainability - which can assist in demonstrating environmental performance in your BREEAM assessments
  • BBA certified


40mm Celotex TB4040 Insulation Storage & Handling

As they are super light and portable, 40mm Celotex TB4040 boards can also be handled and transported easily; making them a doddle to install. If you need to store 40mm Celotex TB4040 insulation boards for a while before installation, you should choose a cool, dry space.

Our rule of thumb when it comes to storage is that the boards should not be stored on the ground. Instead, pop them on a level surface and under a protective cover, just for good measure.

great insulation

Kyle Ritten on

This insulation was used to address thermal bridging I had through some beams in our roof. Great to reduce localised heat losses in our loft. Also very competitive price!
